Question

Accepted Answer

OSI/TCP/IP models are networking models that define how data is transmitted over a network. LAN/WAN refer to local and wide area networks. IP addresses are unique identifiers for devices on a network, while MAC addresses are unique identifiers for network interfaces.

OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.
TCP/IP model is a protocol stack used for establishing communication over a network.
LAN (Local Area Network) is a network that connects computers and devices in a limited area, like a home, office, or building.
WAN (Wide Area Network) is a network that covers a broad area, often connecting multiple LANs.
IP addresses are numerical labels assigned to devices on a network, such as 192.168.1.1.
IP addresses are divided into classes like Class A, B, C, D, and E based on their range and purpose.
MAC address (Media Access Control address) is a unique identifier assigned to network interfaces for communications on the physical network segment.
